- Children and adolescents of both sexes aged 6 - 17 years
- Confirmed diagnosis of ADHD by semi structured-clinical interview K-SADS
- ADHDRS-IV-Parent Version (18-Item-Scale) raw score ≥ 1,5 SD above norm under non-medicated conditions (either drug holiday or prior to medication within the past 6 months)
- Effective treatment with a stable dose of methylphenidate for at least one month (max. 60 mg/day) proved by a 25% symptom reduction in ADHD-RS under medication, compared to retrospective ADHD-RS without medication within the past 6 months.
- Acceptance and capability to swallow capsules of product size, proved by an equally sized placebo provided by Medice®.
- Sufficient knowledge of the German language
- Adequate contraception in case of sexual activity
You may not qualify if:

- Pathological results for vital signs, blood pressure and pulse
- Reported pathological results for ECG during the last 12 months
- Reported pathological results for differential blood count and hepatic metabolism during the last 6 months
- Indication for hospitalization
- Suicidality (assessed by MADRS Item 10, Score ≥ 3)
- IQ \< 70 (clinically assessed)
- Any psychotropic co-medication
- Detention in an institution on official or judicial ruling
